STEERING ASSIST
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the Steering Assist
could result in serious injury or death.
• The Steering Assist is not a replacement
for proper driving procedures and is not
designed to correct careless, inattentive
or absent-minded driving. The Steering
Assist will not always steer the vehicle to
keep it in the lane. It is not designed to
prevent loss of control. It is the driver’s
responsibility to stay alert, drive safely,
keep the vehicle in the traveling lane, and
be in control of the vehicle at all times.
• As there is a performance limit to the
Steering Assist’s capability, never rely
solely on the system. The Steering Assist
does not function in all driving, traffic,
weather, and road conditions. Always
drive safely, pay attention to the opera-
tion of the vehicle, and manually control
your vehicle appropriately.
• The Steering Assist is intended for use on
well-developed freeways or highways
with gentle (moderate) curves. To avoid
risk of an accident, do not use this system
on local or non-highway roads. •
The Steering Assist only steers the ve-
hicle to maintain its position in the center
of a lane. The vehicle will not steer to
avoid objects in the road in front of the
vehicle or to avoid a vehicle moving into
your lane.
• It is the driver’s responsibility to stay
alert, drive safely, keep the vehicle in the
traveling lane, and be in control of the
vehicle at all times. Never take your
hands off the steering wheel when driv-
ing. Always keep your hands on the
steering wheel and drive your vehicle
safely.
• Always drive carefully and attentively
when using the Steering Assist. Read
and understand the Owner’s Manual
thoroughly before using the Steering As-
sist. To avoid serious injury or death, do
not rely on the system to prevent acci-
dents or to control the vehicle’s speed in
emergency situations. Do not use the
Steering Assist except in appropriate
road and traffic conditions.Steering Assist operation
The Steering Assist controls the steering sys-
tem to help keep your vehicle near the center
of the lane when driving. The Steering Assist
is combined with the Intelligent Cruise Con-
trol (ICC) system. For additional information,
see “Intelligent Cruise Control (ICC) (for ve-
hicles with ProPILOT Assist)” (P. 5-84).
The Steering Assist can be activated when
the following conditions are met:
• The ICC system is activated.
• Lane markers on both sides are clearly detected.
• A vehicle ahead is detected (when the ve- hicle is driven at speeds under 37 mph [60
km/h])
• The driver grips the steering wheel.
• The vehicle is driven at the center of the lane.
• The turn signals are not operated.
• The windshield wiper is not operated in the high (HI) speed operation (the steering as-
sist function is disabled after the wiper op-
erates for approximately 10 seconds).

When the Steering Assist is in operation, the
Steering Assist status indicator
O1, the
Steering Assist indicator
O2, and the lane
marker indicator
O3on the vehicle informa-
tion display turn green. A chime sounds when
the Steering Assist initially activates.
When the Steering Assist deactivates, the
Steering Assist status indicator
O1, the
Steering Assist indicator
O2, and the lane
marker indicator
O3on the vehicle informa-
tion display turn gray and a chime sounds
twice.
Lane Departure Prevention (LDP)
When a curve or strong cross wind exceeds
the capabilities of the Steering Assist and
your vehicle approaches either the left or the
right side of the traveling lane, a warning
chime sounds and the LDP indicator light
(orange) on the instrument panel flashes to
alert the driver. Then, the LDP system auto-
matically applies the brakes for a short period
of time to help assist the driver to return the
vehicle to the center of the traveling lane. This
action is in addition to any Steering Assist
actions.

Hands on detection
When the Steering Assist is activated, it
monitors the driver’s steering wheel
operation.
If the steering wheel is not operated or the
driver takes his/her hands off the steering
wheel for a period of time, the warning (1)
appears in the vehicle information display.
If the driver does not operate the steering
wheel after the warning has been displayed,
an audible alert sounds and the warning
flashes in the vehicle information display, fol-
lowed by a quick brake application to request
the driver to take control of the vehicle again.
If the driver still does not respond, the ProPI-
LOT Assist turns on the hazard flasher and
slows the vehicle to a complete stop.
The driver can cancel the deceleration at any
time by steering, braking, accelerating, or op-
erating the ProPILOT Assist switch.
WARNING
Steering Assist is not a system for a hands-
free driving. Always keep your hands on
the steering wheel and drive your vehicle
safely. Failure to do so could cause a colli-
sion resulting in serious personal injury or
death.

NOTE:
If the driver lightly touches (instead of firmly
grips) the steering wheel, the steering
torque sensor may not detect the driver’s
hand(s) on the steering wheel and a sequence
of warnings may occur. When the driver
holds and operates the steering wheel again,
the warnings turn off.
Steering Assist limitations
WARNING
• In the following situations, the camera
may not detect lane markers correctly or
may detect lane markers incorrectly and
the Steering Assist may not operate
properly:
– When driving on roads where there
are multiple parallel lane markers,
lane markers that are faded or not
painted clearly, nonstandard lane
markers, or lane markers covered
with water, dirt, snow, etc.
– When driving on roads with discon-
tinued lane markers
– When driving on roads with a widen-
ing or narrowing lane width –
When driving on roads where there
are multiple lanes or unclear lane
markers due to road construction
– When driving on roads where there
are sharply contrasting objects, such
as shadows, snow, water, wheel ruts,
seams, or lines remaining after road
repairs (the Steering Assist could de-
tect these items as lane markers)
– When driving on roads where the
traveling lane merges or separates
• Do not use the Steering Assist under the
following conditions because the system
may not properly detect lane markers.
Doing so could cause a loss of vehicle
control and result in an accident.
– During bad weather (rain, fog, snow,
dust, etc.)
– When rain, snow, sand, etc., is thrown
up by the wheels of other vehicles
– When dirt, oil, ice, snow, water, or an-
other object adheres to the camera
unit
– When the lens of the camera unit is
foggy
– When strong light (for example, sun-
light or high beams from oncoming
vehicles) shines on the camera –
When the headlights are not bright
due to dirt on the lens or the head-
lights are off in tunnels or darkness
– When a sudden change in brightness
occurs (for example, when the vehicle
enters or exits a tunnel or is under a
bridge)
– When driving on roads where the
traveling lane merges or separates or
where there are temporary lane
markers because of road
construction
– When there is a lane closure due to
road repairs
– When driving on a bumpy road sur-
face, such as an uneven dirt road
– When driving on sharp curves or
winding roads
– When driving on repeated uphill and
downhill roads
• Do not use the Steering Assist under the
following conditions because the system

parts
– When an object that obstructs the
camera unit detection range is
attached
– When excessively heavy baggage is
loaded in the rear seat or luggage
area of your vehicle
– When the vehicle load capacity is
exceeded
• Excessive noise will interfere with the
warning chime sound, and the beep may
not be heard.
• For the ProPILOT Assist system to oper-
ate properly, the windshield in front of
the camera must be clean. Replace worn
wiper blades. The correct size wiper
blades must be used to help make sure
the windshield is kept clean. Only use
Genuine INFINITI wiper blades, or
equivalent wiper blades, that are specifi-
cally designed for use on your vehicle
model and model year. It is recommended
that you visit your INFINITI retailer for
the correct parts for your vehicle.Steering Assist temporary standby
Automatic standby due to driving operation:
When the driver activates the turn signal, the
Steering Assist is temporarily placed in a
standby mode. (The Steering Assist restarts
automatically when the operating conditions
are met again.)
Automatic standby:
In the following cases, a warning message is
displayed along with the chime, and the
Steering Assist is placed in a temporary
standby mode. (The Steering Assist restarts
automatically when the operating conditions
are met again.)
• When lane markers on both sides are no longer detected
• When a vehicle ahead is no longer detected under approximately 37 mph (60 km/h)
Steering Assist cancel
Under the following conditions, the Steering
Assist cancels, and the Steering Assist status
indicator and the Steering Assist indicator
turn off: • When unusual lane markers appear in the
traveling lane or when the lane marker can-
not be correctly detected for some time due
to certain conditions (for example, a snow
rut, the reflection of light on a rainy day, the
presence of several unclear lane markers)
• When the windshield wiper operates in the high (HI) speed operation (the Steering As-
sist is disabled when the wiper operates for
more than approximately 10 seconds)
NOTE:
For vehicles with auto wipers, the wipers
may automatically switch to LO or HI. If the
auto wipers remain in LO or HI for longer
than 10 seconds, the steering assist will
cancel.
Action to take:
Turn the ICC system off using the CANCEL
switch. When the conditions listed above are
no longer present, turn the ICC system on
again.
Steering Assist malfunction
When the system malfunctions, it turns off
automatically. The Steering Assist status
warning illuminates (orange). A chime may
sound depending on the situation.
Starting and driving5-99
Page 346 of 526
Action to take:
Stop the vehicle in a safe location, place the
vehicle in the P (Park) position, turn the en-
gine off, restart the engine, resume driving,
and set the Intelligent Cruise Control system
again. If the warning (orange) continues to
illuminate, the Steering Assist is malfunction-
ing. Although the vehicle is still drivable under
normal conditions, have the system checked.
It is recommended that you visit an INFINITI
retailer for this service.
Steering Assist maintenance
The camera sensor is located above the in-
side mirror.
To keep the proper operation of the system
and prevent a system malfunction, be sure to
observe the following:
• Always keep the windshield clean.
• Do not attach a sticker (including transpar-ent material) or install an accessory near
the camera unit.
• Do not place reflective materials, such as white paper or a mirror, on the instrument
panel. The reflection of sunlight may ad-
versely affect the camera unit’s capability
of detecting the lane markers. • Do not strike or damage the areas around
the camera unit. Do not touch the camera
lens or remove the screw located on the
camera unit.
If the camera unit is damaged due to an
accident, it is recommended that you visit an
INFINITI retailer.

CONVENTIONAL (fixed speed)
CRUISE CONTROL MODE
NOTE:
ProPILOT Assist provides no approach
warnings, automatic braking, or steering as-
sist in the conventional (fixed speed) cruise
control mode.
This mode allows driving at a speed between
25 to 90 mph (40 to 144 km/h) without
keeping your foot on the accelerator pedal.
WARNING
• In the conventional (fixed speed) cruise
control mode, a warning chime does not
sound to warn you if you are too close to
the vehicle ahead, as neither the pres-
ence of the vehicle ahead nor the vehicle-
to-vehicle distance is detected.
• Pay special attention to the distance be-
tween your vehicle and the vehicle ahead
of you or a collision could occur.
• Always confirm the setting in the ICC
system display.
• Do not use the conventional (fixed
speed) cruise control mode when driving
under the following conditions:
– When it is not possible to keep the
vehicle at a set speed –
In heavy traffic or in traffic that var-
ies in speed
– On winding or hilly roads
– On slippery roads (rain, snow, ice,
etc.)
– In very windy areas
• Doing so could cause a loss of vehicle
control and result in an accident.
Conventional (fixed speed) cruise
control switches

To resume the preset speed, push and release
the RES+ switch. The vehicle will resume the
last set cruising speed when the vehicle speed
is over 25 mph (40 km/h).WARNING
Failure to follow the warnings and instruc-
tions for proper use of the RAB system
could result in serious injury or death.
• The RAB system is a supplemental aid to
the driver. It is not a replacement for
proper driving procedures. Always use
the side and rear mirrors and turn and
look in the direction you will move before
and while backing up. Never rely solely
on the RAB system. It is the driver’s re-
sponsibility to stay alert, drive safely,
and be in control of the vehicle at all
times.
• There is a limitation to the RAB system
capability. The RAB system is not effec-
tive in all situations.
• Inclement weather or ultrasonic sources
such as an automatic car wash, a truck’s
compressed-air brakes or a pneumatic
drill may affect the function of the sys-
tem; this may include reduced perfor-
mance or a false activation.
The RAB system can assist the driver when
the vehicle is backing up and approaching
objects directly behind the vehicle. The RAB system detects obstacles behind
the vehicle using the parking sensors
O1lo-
cated on the rear bumper.
NOTE:
You can temporarily cancel the sonar func-
tion in the vehicle, but the RAB system will
continue to operate. For additional informa-
tion, see “Front and rear sonar system”
(P. 5-147).
